This is caused by a Nix upgrade on the build farm machines. Builds now run in a
user namespace, which confuses some of them. I've applied aszlig's seccomp patch
(https://github.com/NixOS/nix/pull/1131) which fixes some problems (like the go
build).

This one seems to be confused by setuid/setgid not working as expected, which is
hard to avoid in a user namespace with only one uid...

[Nix-dev] Hydra.nixos.org: new EPERM errors

[Vladimír Čunát]

Hi Eelco & Rob! (or who else co-maintains the build farm)

Recently I see new EPERM errors in check-phases of some packages on
staging, and apparently the problems aren't "caused" by any nixpkgs
commits but by the build slaves themselves, perhaps some change in the
way nix sets up chroots in there.

I could never reproduce the problems locally (I don't run very new
nix-daemon), but on Hydra they seem to always happen.  Any idea about
what exactly causes them?  It might be best to resolve that nix setting
instead of tweaking tests of individual packages...

Examples:
http://hydra.nixos.org/job/nixpkgs/staging/go_bootstrap.x86_64-linux
http://hydra.nixos.org/job/nixpkgs/staging/libuv.x86_64-linux
